Fisher C1 Pneumatic Controller

Honeywell UDC2500 Electronic controllerPressure controllers can be electronic or pneumatic. Electronic controllers require AC or DC power and analog or digital electronic inputs. They compare the measured pressure input to a set point and provide an electronic output to a control valve or other device to bring to measured pressure to the set point.

Pneumatic controllers usually directly measure the pressure in a popeline or other vessel, compare it to the pressure setpoint, and provide a pneumatic output to a control valve or other device to bring the measured pressure to the setpoint. The pneumatic controller is often mounted on the control valve.
